Use the given graph of the function f to answer the following questions. 1. Find the open interval(s) on which f is concave upward. Answer (in interval notation): 2. Find the open interval(s) on which f is concave downward. Answer (in interval notation): 3. Find the coordinates of the points of inflection. List your answers as points in the form (a, b). Answer (separate by commas):

Step 1
This means that the second derivative of the function is positive. We can see from the graph that this happens between x = -2 and x = 0, and also between x = 2 and x = 4. So the answer is: (-2, 0) U (2, 4) 2) Show more…

The graph of the derivative f' of a function f is shown below. Use the graph to answer the questions. a) On what intervals is the function f increasing or decreasing? b) At what values of x does f have a local maximum or minimum? c) On what intervals is f concave upward or downward? d) State the x - coordinate(s) of the point(s) of inflection e) Assuming that f(0) = 0, sketch a graph of f
